What's more, the compact 12-point nut version lets you easily slip a socket close to the pipe. Each  bolt kit includes the specific number of parts for your application, plus premium-quality washers and hex or 12-point nuts, as required. Both the black oxide finished chrome moly and stainless steel are rated at 170,000 psi.
